Box jellyfish occur near beaches and near river estuaries from October to April north of 1770. They can occasionally be found outside these times. The previous text is in English. Here is a translation to Swahili:
Viwavi wa baharini hutokea karibu na pwani na karibu na midomo ya mto kuanzia Oktoba hadi Aprili kaskazini mwa 1770. Wakati mwingine huenda wakapatikana nje ya nyakati hizi.
